How does the all-wheel steering on the Audi A8 improved handling?

I've heard that the Audi A8 has all-wheel steering, but what does that actually mean for the car's handling? Can it really make a noticeable difference in driving? I'm interested to hear from someone who has experienced it firsthand.

The all-wheel steering on the Audi A8 allows the rear wheels to turn in the opposite direction of the front wheels at low speeds, reducing the car's turning radius and making it easier to maneuver in tight spaces. At higher speeds, the rear wheels turn in the same direction as the front wheels, providing better stability and handling. As someone who has owned an A8 with this feature, I can attest that it definitely makes a difference in daily driving.
